Technical Field

The invention relates to the technical field of high polymer materials, in particular to steel wire belt surface glue for a steel wire belt of a drum vulcanizer.

Background

The steel wire belt of the drum vulcanizer is responsible for the pressure application and transportation functions of the drum vulcanizer and is an important part for maintaining the service life of the drum vulcanizer. With the rapid development of the adhesive fabric products, the steel wire belt of the drum vulcanizing machine meets the vulcanizing requirements of the adhesive fabric products from the initial stage to the current multifunctional purposes of adhesive fabric compounding, transfer printing camouflage and the like, and can be used under the harsh conditions of large load for a long time, high temperature, frequent deflection, corrosion resistance and the like.

The steel belts of the drum-type vulcanizing machine in the market are all steel belts without rubber, only have a single rubber vulcanization function, and when the steel belts without rubber are used for compounding and transferring the adhesive tapes to camouflage colors, the camouflage films or the adhesive tapes are easily worn and damaged by hard steel belts, and the service life of the steel belts can be shortened. At present, some enterprises use rubber steel wire belts, but due to the limitation of the formula, the rubber steel wire belts are easy to wear, generate large heat, delaminate and bulge in the using process, and the steel belt can also break in the high-speed running process.

The invention aims to overcome the defects of the prior art and provides a steel wire belt surface adhesive for a steel wire belt of a drum vulcanizer.

The technical scheme for realizing the purpose of the invention is as follows:

the steel wire belt surface adhesive for the steel wire belt of the drum vulcanizer is different from the prior art in that the steel wire belt surface adhesive is prepared from the following raw materials in parts by weight: 80-90 parts of chlorinated butyl 1066 rubber, 10-20 parts of chloroprene 120 rubber, 10-20 parts of wear-resistant carbon black N33010-20 parts, 15-25 parts of semi-reinforcing carbon black, 40101-2 parts of anti-aging agent, 4-5 parts of zinc oxide, 2-4 parts of magnesium oxide, 1-2 parts of stearic acid, 0.6-1.0 part of sulfur, 0.8-1.2 parts of thiazole accelerator DM and 2.2-2.8 parts of tetramethyl thiuram disulfide accelerator TMTD.

The preparation process of the steel wire belt surface adhesive comprises the following steps: the rubber is prepared by matching the raw materials according to the weight ratio, mixing the raw materials by an internal mixer to prepare rubber compound, preparing the rubber compound into rubber sheets by a calendar extrusion mode, uniformly coating an adhesive on a steel wire belt of a drum vulcanizer, then pasting the rubber sheets on a steel wire belt belted layer, gradually preparing a steel wire belt rough blank by belt surface dotting and analogy, rolling a tire blank by a vulcanizer at normal temperature for 3 days, gradually heating according to the process requirement, vulcanizing the steel wire belt surface rubber, continuously polishing protruding parts and repairing missing parts in the vulcanizing process, and forming a steel wire belt surface rubber finished product after the steel wire belt surface rubber is completely vulcanized.

The chlorinated butyl rubber prepared by introducing chlorine into a butyl rubber solution not only retains the inherent performance characteristics of butyl rubber, but also can be used with various rubbers to produce various rubber products.

The steel wire belt surface glue raw material adopts the chlorinated butyl 1066 rubber, overcomes the defects that the butyl rubber is slow in vulcanization speed, poor in adhesive property and difficult to use with other rubbers, and the like, has the characteristics of good air tightness, good elasticity, good heat resistance, excellent acid and alkali resistance and the like, and is beneficial to improving the heat resistance, fatigue resistance, corrosion resistance, adhesion and the like of the steel wire belt surface glue.
